项目历史

Backblaze maintains the tool in the Backblaze/B2_Command_Line_Tool repository and publishes it as a Python package, standalone binaries, Docker image, and Homebrew package. The README describes it as command-line access to all capabilities of the B2 service.

The CLI has evolved across API-versioned command surfaces. The README documents the current guidance: use `b2` for the latest stable interactive interface, and use version-bound commands such as `b2v4` for long-running scripts that need stable behavior.

采用历史

B2 users adopted the CLI because object storage needs scriptable upload, download, sync, lifecycle, and key-management workflows. Backblaze's official docs recommend Homebrew as the quickest setup path for Mac users, while the input package facts also list apk and Scoop packages.

The tool is common in backup scripts and CI jobs because B2 is frequently used as low-cost object storage. Its versioned command aliases are especially package-nerdy: they let a package ship a newer implementation while preserving an older command contract for scripts.

使用方式

Typical usage starts with account authorization, then commands such as `b2 bucket list`, `b2 file upload`, `b2 ls`, `b2 sync`, and `b2 key create`. The official README and Backblaze docs state that `B2_ACCOUNT_INFO` selects the SQLite cache file for authentication information and that the default is `~/.b2_account_info`.

For containers, the README shows either passing `B2_APPLICATION_KEY` and `B2_APPLICATION_KEY_ID` each run or persisting authorization state in a mounted volume.

为什么软件包爱好者会关心

For package nerds, `b2-tools` is a neat collision between package name, executable name, and API-versioned command names: Homebrew installs `b2-tools`, users run `b2`, and scripts may choose `b2v4` for compatibility.

It is also a Python CLI with official binary and Docker distribution, so packaging choices affect startup time, dependencies, credential cache placement, and whether users get the newest API surface or a stable alias.
